Advice 1: How to connect two light bulbs

All electrical work should be carried out in accordance with the schemes and with maximum safety for their own life and health. Connecting cables incorrectly may cause a short circuit and fire. So, if you've never dealt with connecting wires, entrust it to a professional electrician. If you think that will cope with this task yourself, then make the connection of the two lamps or groups of lamps in accordance with the rules.

Before you begin to connect cables to a group of bulbs, turn off the electrical panel that supplies the power to the apartment.

2

All wires connected to the switch and bulbs, spread in different directions. Then turn on the power supply to the instrument.

3

Check the indicator with a screwdriver or a device where the phase wire and zero wire. If bringing a device, the lamp lights, it is a phase wire, if the lamp is not lit – zero. In some transactions there are 4 wires, one of which connects to ground.

4

All wires extending from the bulbs and the switch, strip the insulation. As already stated above all it must be off panel power supply.

5

If you want to have two bulbs lit up simultaneously by pressing a single key in the switch, then connect the two phase wires on the bulbs to the phase conductors of the switch.

6

The neutral wire are connected with zero. If in addition, there is a ground wire, it is necessary to connect the bulbs with the ground wire of the switch.

7

If you need to have two light bulbs were included from different keys circuit-breaker, the phase wire one light bulb is connect to the phase conductors of a single key. Similarly, connect the second light bulb.

8

Neutral wires connect together and go to the neutral wire of the switch. The ground wire is also twisted.

9

After all connections are made and connections invite a professional electrician to check the correctness of the produced wiring diagrams and only after that can use lights.

Advice 2: Why blow up light bulb

The good old light bulb of Ilyich – a favorite bomb of all Soviet schoolchildren. Everyone knows that if you break a bulb, then you hear a loud Bang. But sometimes a cotton happens in the apartment when a light bulb burst immediately after turning on the light. The reasons, however, are common.

Incandescent lamp is a complicated device. It works, heating up in the result of electrical current flow in a spiral from alloys based on tungsten. For the manufacture of conventional light bulbs require a minimum of 7 metals, and the bulb of most modern lamps filled with inert gases, except for lamps of low power. These lamps (25 Watt) make vacuum.Everyone is aware of the explosion of the light bulb is nothing like the stabilization of the atmospheric pressure during decompression of the bulb. Often a sharp filling with air discharged environment the bulb can even lead to the destruction of its surface, that's why the fragments of the lamps and sometimes flying in all directions.Another question, why is a sealed lamp filled with rarefied inert gases, or vacuum is suddenly depressurized. Reasons for this may be several, but the main is substandard products, lamps, the Assembly of which was made a technological error. Another common problem of the Russian apartments – high voltage electrical networks. The lamp life depends on the quality of the supply voltage. With an increase in voltage increases the temperature of the tungsten filament, the tungsten atoms begin to evaporate intensively, the filament thins, there is a darkening of the bulb and eventually the filament breaks. In this regard, you should pay attention to the contacts in the bulb sockets, which can also shorten the life of any lamp.Finally, to trigger the explosion of a lamp in your apartment can banal defective or broken switch defective connection of wires of the chandelier to the network and for poor connections in the distribution boxes or fuse box housing. If you find a problem of constant explosions of lamps in your apartment, but do not have special education and corresponding experience, then work to correct the status quo is best put on the shoulders of the electrician.

Advice 3: How to connect multiple light bulbs

One of the main requirements for the lighting of premises – functionality and efficiency. To ensure the apartment comfortable lighting, it is recommended to use the combined connection diagrams, while the luminous flux it is desirable to make controlled power. One of the ways to do lighting – connect multiple light bulbsthat will be included in a specific pattern.

You will need

lamp (chandelier);

bulbs;

- connecting wires;

- the probe (the tester).

Instruction

1

Before production work on the installation of ceiling lights make sure that mains voltage is disconnected. Use this to check the tester or test lamp. Only after such verification, the luminaire should be mounted on a ceiling hook. Use for mounting a portable stable step-ladder. If necessary, make sure that during the production of works for connection of lighting you are insured assistant.

2

In the simplest case, apply the usual method of connecting a ceiling fixture or chandelier using a two-wire circuit in which all bulbs are included simultaneously. Wiring this connection is not straightforward.

3

If the chandelier is for five or more bulbs, mount the three-wire scheme. It will consist of one common wire and two sectional wires. For easy installation use the wires in the braid of a different color - this will help to avoid mistakes when connecting the scheme to the food.

4

In the presence of a series switch to make a circuit of light bulbs "2-3-5". This option allows you to use multiple methods to enable mnogoplanovo lamp, wherein the switch enables you to control the connection of lamps. In other words, you can only turn two lights, three only, and include all five lamps.

5

When mounting diagram with labeled wires connect the common wire of the chandelier and the neutral wire connected to the hook on which the chandelier is suspended. Phase hoses connect the hook with sectional wires. If the wires are not color coded, to installation, determine zero and phase wires with a probe. This will apply for wire tension, so be extremely careful. After identifying the purpose of the wire again, cut off the voltage and perform the circuit.

6

To all the lamps in the lamp was started at the same time, use the switch with one button, and the wires 2 and 3 (see figure in step 3) connect together and connect to the phase liner.

7

Connecting wires, install lights and attach the cartridges in the bulb. Connect the voltage and test the installed circuits. If necessary, correct any errors in the installation.
